Hello to all, I was wondering if anyone has used the Hyper tech Power Programer? I have 98 Silverado with a 5.7 liter(350cc) that I will be using to pull a R.V. trailer, they claim it will give you 20 more horsepower. My next question is; by increasing horsepower will I get better fuel economy? Thank you......... Ed
